Norfolk Southern train derailment causes oil spill

A Norfolk Southern train transporting crude oil from Canada that was traveling between Chicago and New Jersey derailed Thursday in western Pennsylvania, forcing 21 of its 120 cars off the track, according to Reuters.
It’s been reported that four of the cars spilled in the range of 3,000 to 4,000 gallons. Nineteen of the 21 cars that derailed were loaded with crude oil. No injuries occurred.
The cause of the derailment is unknown.
Rail transportation of crude oil has been in the news nearly constantly because of a rash of train derailments, which started with a Montreal, Maine & Atlantic Railway accident in Quebec last July. These incidents have lead to regulatory investigations in Canada and the United States.
